Don't you mean the CDN that CloudWay offers and not CloudFlare?
Don't host with Cloudway's ... does look interesting in that customers get to choose Google or Amazon or ... other?
Free to start ... plans offer .x per hour or montly and based upon the specs of the option chosen.
What are you serving from your Moodle? A lot of videos then one might benefit by CloudWays CDN .... cost does push up the overall a little, though.
Wouldn't be interesting if Moodle.org started tracking with what cloud provider registered moodle sites were hosted?
Bottom line response I guess is .... up to you!
